This means that when I put on the headset, the system can instantly identify me as a unique user and call up my preferences (customized environment, content library, game progress, settings etc) and when my friend puts on the HMD, the system loads their saved data.Įye-tracking analytics provide valuable insights into user attention which aids developers in understanding how their application is being used. This makes eye-tracking perfect for setting up multiple user profiles across a single headset. In addition to detecting movement, eye-tracking could also be used as a biometric identifier.
This has implications for secure design review as well as a myriad of other security conscious functions. In the same way that Iris scanning is used to unlock your phone or your secure door locks, eye tracking technology could enable true “eyes-only” information security. This can also have vergence implications to reduce eye strain over a longer period of time, but this will require advanced lens technology to be added as well. Knowing your IPD is important in VR because it’s required to move the lenses and displays into the optimal position for both comfort and visual quality. They will gain the ability to read faces and emotions, and in turn, have their own reactions analyzed by the game AI to affect their response and outcome.īy calculating the user’s inter-pupillary distance (IPD) devices can automatically adapt to the user. Multiplayer environments become richer as characters and virtual avatars can read more than just body language of other players within virtual worlds. This approach can help lower GPU load and power consumption significantly, allowing manufacturers to increase both screen resolutions and refresh rates.
Foveated rendering is a process that works by only rendering the specific part of the screen where the user is currently looking in full resolution - a similar way to how the human eye works.
Officially, the Facial Tracker only fits on Vive Pro headsets, but with a 3D printer, you can make it work with any headset.Eye-tracking makes it possible for devices to reduce GPU load and/or deliver a higher-quality graphics experience through foveated rendering. The Vive Facial Tracker is designed to pair with HTC’s Vive Pro lineup, and when paired with the Vive Pro Eye, you can animate your entire virtual face. Still, in a multi-user collaboration or training solution, it’s the difference between making eye contact with who you’re talking to or interacting with an expressionless avatar. In a gaming experience, that’s not very important. It also gives your virtual avatar a more natural appearance by giving them animated eyes that map your own. Eye-tracking in VR has several benefits, including performance improvements, heat mapping, and attention analysis. Last year, we started working with the Vive Pro Eye, a VR headset from HTC that includes built-in eye-tracking cameras from Tobii. Until now, the expressive side of communication has never been possible in VR. You can tell when people are interested or not, excited, or bored, or if they’re happy, sad, angry, or annoyed, just by the expressions on their faces. Our expressions often tell people more about our emotions than our words. It maps your lips, tongue, chin, and cheeks, which allows you to bring all your facial expressions into virtual environments.įacial expressions are an essential part of human communication. The device attaches to your VR headset and hangs in front of your mouth to capture every facial expression. The Vive Facial Tracker is a small peripheral with two infrared depth cameras designed to map the movements of your face.
